The Guardian Open Platform launches, with their Content API, their Data Store, and a selection of client libraries for the API (one of which I did a smidge of work on). This is not just a good thing, it's a good thing Done Right, and I'm looking forward to what's next from the Open Platform team.

Custodian is the Ruby gem for accessing the Guardian Open Platform Content API that James Darling, Kalv Sandhu, and I (although my contribution was minor) built. There's a Google Code link to it, but I'd imagine the github version is where the action will be.
